Arsène Wenger has been handed a major boost in Arsenal's bid to win the Premier League title with several of his players returning from injury before Saturday's visit of Blackburn Rovers. Cesc Fábregas, Theo Walcott, Alex Song and Abou Diaby are back, while Wenger is optimistic that Robin van Persie, Nicklas Bendtner and Aaron Ramsey will be able to take part.

"[They] will be available," the Arsenal manager said regarding Fábregas, who has recovered from his latest hamstring problem, Walcott (ankle), Song (knee) and Diaby (groin). "I have not decided if they will start the game yet but they will all be available.

"Van Persie has a good chance, too. He has a final assessment tomorrow but we believe he will be fit. It is a bruised knee. Nicklas Bendtner is in the same situation. He will have a test tomorrow on his ankle and we'll see. In fact, we have a few players with tests tomorrow – Ramsey with his groin, Bendtner, Van Persie. I will make a decision after training in the morning."

Van Persie also took a blow to his thigh while playing for Holland in the Euro 2012 qualifier against Hungary, while Bendtner's injury came on international duty for Denmark.

Wenger said that beyond his long-term injured – who include Manuel Almunia, Lukasz Fabianski, Wojciech Szczesny, Thomas Vermaelen and Emmanuel Frimpong – only Denílson is definitely unavailable. Arsenal hope to maintain the pressure on Manchester United, who are five points clear at the top. Wenger added: "We just have Denílson out. It is short–term. We have one or two players with question marks but all the other players will be available."

With Arsenal having won only one of their past six matches, Sébastien Squillaci has called on the squad to show their quality. He said: "It is a bit of a bad time that we're having but we have all got to get our chins up and show our mettle against Manchester United for the title. That's the remaining target now and we've got to give everything for the cause."
